i tried several different external soundcards, and it is getting sent from the PC into both the live audio and the ground via the PSU as I tried removing the ground loop. I think the PSU is sending this crap everywhere due to the mains filter picking up radiated RF and feeding it back into the ground,

out of curiosity, Just had a quick look on the scope (was really fiddly as the probes are them new politically correct sort what are supposed to stop you getting electrocuted) and the output of the laptop PSU is fucking filthy, there’s regular spikes of several milivolts superimposed on the DC on a waveform which is full of harmonics (the scope couldn’t even trigger properly on it but I could just about see the amount of shite coming out of this PSU..
